Tityos

Tityos or Tityus (Greek: Τιτυός) was a giant from Greek mythology.

Tityos was the son of Elara; his father was Zeus. Zeus hid Elara from his wife, Hera, by placing her deep beneath the earth. Tityos grew so large that he split his mother's womb, and he was carried to term by Gaia, the Earth. Once grown, Tityos attempted to rape Leto at the behest of Hera. He was later slain by Artemis and Apollo. As punishment, he was stretched out in Tartarus and tortured by two vultures who fed on his liver, which grew back every night. This punishment is comparable to that of the Titan Prometheus.

Jane Ellen Harrison noted that, "To the orthodox worshipper of the Olympians he was the vilest of criminals; as such Homer knew him":

In the early first century, when the geographer Strabo visited Panopeus (ix.3.423), he was reminded by the local people that it was the abode of Tityos and recalled the fact that the Phaeacians had carried Rhadamanthys in their boats to visit Tityos, according to Homer. There on Euboea at the time of Strabo they were still showing a "cave called Elarion from Elara who was mother to Tityos, and a hero-shrine of Tityos, and some kind of honours are mentioned which are paid him." It is clear that the local hero-cult had been superseded by the cult of the Olympian gods, an Olympian father provided, and the hero demonized. A comparable giant chthonic pre-Olympian of a Titan-like order is Orion.
